To all whom it ma 3 concern:

Be it known that I, GEORGE Roi-1min, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Roof Fire-Extinguishers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to a fire extinguishing apparatus, and the primary object of the invention is to provide means whereby the roof of a house may be flooded with water, in case of fire, and also to provide means whereby either one side or the other side of a roof may be flooded with water independently of the opposite side.

More specifically, the object of this invention is to provide a pair of pipes which extend along upon each side of the comb of a house roof, and which have slots extending their full lengths substantially parallel with the roof, so as to permit water to exit from the pipes over the roof for the purpose of flooding the latter in case of fire;

"and further to provide a three-way valve which is positioned at the point of communication between'the two pipes and the feed pipe for controlling the passage of the water into either of the comb carried pipes, or into both of them as desired.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawin s wherein like characters designate like an corresponding parts throughout the several views, and in which Figure 1 is a view of a house showing the invention applied;

Fig. 2 is a fragmentary top plan view of the invention; I

Fig. 3 is a section through the ground showing the feed pipe extending therein andalso illustrating the valve for controlling the operation of the extinguisher;

Fig. 4 is a section through the three-way valve construction;

Fig. 5 is an end elevation of the valve construction; and

Fig. 6 is a section on the line 6(3 of Fig. 1.

Referring more particularly to the drawings, l designates the roof of any ordinary house. which roof has an angle iron 2 mounted over the comb of the roof 1, and extending downwardly upon each side of the roof as clearly shown in Figs. 1 and 6 of the drawings. The pipes 3 and 4 extend along the comb of the roof 1 and the pipe 3 is positioned upon one side of the comb while the pipe 4 is positioned upon the other side, as clearly shown in Fig. 6 of the drawings. The ends of the pipes 3 and 4 are joined as shown at 5 and 6. The pipes 3 and 4 have a cap or plug 5 inserted therein, at the joined ends 5 of the pipes, for preventing the water from flowing from the pipe 3 into the pipe 4, when it is desired to flood only one side of the roof of the building. The pipes 3 and 4 are provided with longitudinally extending slots 7, which are substantially parallel to the comb of the roof of the house, so that water flowing out of the pipes will flow over the roof for flooding the same, in case of fire. The ends 6 of the pipes 3 and 4 are connected to a valve casing 8. as clearly shown in Fig. 4 of the drawings. The casing 8 has a valve 9 positioned therein which is provided with a plurality of passageways A. B, C. D, E and F. The feed pipe 10 also communicates with the casing 8,-as clearly shown in Fig. 4. When the passageway A is in communication with the feed pipe 10,

and the passages B and C in communication with the pipes 3 and 4 respectively. water will be fed to both of the pipes 3 and 4, and when the passageway E is in communication with the feed pipe 10 and the passageway D in communication with the feed pipe 3, which positions are provided by the rotation of the valve 9. the water'will be directed only through the pipe 3 and when the passageway F communicates with the pipe 10 and the passageway D communicates with the pipe 4, water will be fed only to the pipe 4, so that by the operation of the valve, the passage of the water outwardly over the roof 1 may be controlled as desired.

The valve 9 projects out of the casing 8, and it has a rod 12 extending diametrically therethrough. Downwardly extending rods 14 and 15 are connected to the ends-of the rods 12 and are provided for rotating the valve 9 for controlling the positions of the various passageways or ducts formed valve, and oonseqnently controlling the sage of the Water through the pipe one e,

alon one end oi? the house, and into the ground, as clearly shown in ot the drawings. The lower end of t' 1 feed pipe 10 is positioned in :1 he or suitable structure indicated at 19, which is ro Yided preventing the freezing of the =YfllV structure 520 Whieh controls the gossage of Water into the feed pipe 10. t 21 extends nnwerdl thron n on ooenine 22 in the ground, and it has a handle 23 formed thereon, through the medium o which handle and rod the mine is o; sted for controlling t is passage of me into and through the pipe 10.

The i'sli'e 20 has a pipe 12% communicating therewith which supplies the Water to valve and the pipe 10 end this pipe may connected to an ordinary water i a pump, through the medium is depending upon the manner in which the Water is procured tor the house.

in ease of a tire on the roof of the house, the valve 520 is opened, through operation of the rod 21, Wlioh allows t e pass upwardly throngl the feed. A

in reducing the invention to practice, cer tain lninor features 01 construction, combination and arrangement of parts may necessitate alterations to which the patentee entitled, provided such alterations are comprehended Within the scope of what is *lzizned.

il hat is e'laiined is in e fire extinguisher for roots, a pairof pipes extending longitudinally along the comb of a house root, one of the said pipes being positioned upon each side of the comb, said pipes provided Witlrlongitudinelly e1:- tending slots parallel to the comb oi? the root for flooding the root with Water upon pessage of Water into the pipes. a feed pipe for delivering; Water to said roof carried pipes, 11 mire easing connecting the root carried pines and the teed nipe, rotary valve loositioned in the said casing, said volve being; orovided with a series of passage Ways, said mire havi one end projecting outwardly from said casing, a rod extending diametrically through the outwardly projecting portion of the valve, and means connected with the 521d rod to coo 'ol the passage Ways or the valve when admitting Water to the root carried pipes as and for the purpose snecilied.
